The achievability of acoustic quality of floor slabs in wood constructions is a challenge due to the low mass and stiffness. The increased sound transmission in the low-frequency range typical of lightweight construction can lead to discomfort among users. Optimization approaches often result in suboptimal solutions, such as adding additional mass and stiffness in the form of concrete elements. These approaches are at odds with modern demands in construction and architecture, as well as with the advantages of wood, which are characterized by sustainability and low dead weight. In contrast to the conventional planning process, the Cluster of Excellence IntCDC at the University of Stuttgart has the investigation of integrative approaches (co-design) as a central objective. This is to lay the methodological foundations for a modernization of building design. With co-design and with the help of novel digital technologies and both design and planning techniques, innovative solution concepts can be developed that improve the vibration behavior of floor slabs and retain the environmental benefits of wood. This enables the consideration of ecological challenges in terms of a holistic and digital planning process to contribute to the creation of a quality and sustainable built environment. Theresa Müller, M. Sc., and Roberta Di Bari, M. Sc., two doctoral students from the faculty's Institute for Acoustics and Building Physics (IABP), will report on their research results in a presentation at the DAGA 2022 - Jahrestagung für Akustik (Annual Conference for Acoustics).
